With this In-Home Fireworks Theater, you can now say, "Happy New Year!", "Happy Birthday, America!", and "Happy Sweet 16, spoiled brat with a rich daddy!" 365 days a year. From the comfort of your own living room, no less. Sega Toys, purveyors of the Bathtub Planetarium, have revamped their light show into fiery bursts, and added the ocular thrills of animation and the aural stimulation of sound effects. All that's required--aside from $250 for the projection device--is an empty wall and a shroud of darkness.

Note: The In-Home Fireworks Theater ships directly from Japan, and is apparently intended exclusively for the Japanese, as instructions for use do not come in English. Operation, however, seems to be no more extensive than flipping an On/Off switch, so 40%, maybe 50% of us should be able to figure it out without a written step-by-step.

Celluon takes a slightly more humble route, bragging only about its PicoPro's ability to fit in your pocket, but SK Telecom goes straight for the pinnacle of accomplishment, calling its UO Smart Beam Laser Projector The...

Now that we're all adequately equipped to take selfies everywhere we go, the iCODIS mobile projector would like to facilitate our ability to play them back at any moment as a slideshow. For friends at a house party. For...

Holus shows you your board game. Your model. Your mama. In a form condensed to the size of your tabletop, enhanced to 3 dimensions, and manipulated by the powers of technology and Grayskull into a holographic image. Holus...

They say it's a pocket-sized movie theater, but I bet Celluon's PicoPro projector will mostly be relegated to boring applications like office presentations and impromptu TED talks at Palo Alto Starbucks stores. If I got...

The Celluon Virtual Keyboard gets a mouse playmate. A Norse God of War mouse playmate. The ODiN Aurora says it's the World's First Projection Mouse, meaning it beams a hi-res 8cm x 8cm box onto the area where you would...

Bathe with the stars! Well, the battery-operated, not the hydrogen and helium gas, kind. Or the Jennifer Lawrence/Ryan Gosling kind for that matter. Still, the Homestar Spa, a planetarium for the bathtub, hot tub, or...
